保护眼睛的英语作业【实用20篇】

How to protect the environment

Good environment can make people feel happy and fit . To improve the environment means to improve our life.

We should plant more trees and flowers around us . We shouldn’t cut them down . We should stop factories from pouring waste water into the river and waste gas into the air.

Whenever we see litter on the ground , we should pick it up and throw it into dusbins. Never spit in public. Don’t draw on public walls. It’s our duty to protect the environment.

Do you know? Time unknowingly. Have you found? Our home into a another look: the bottom of the river became a filth, dirty dust filled the air, everywhere... This is what caused the so huge change? Turned out to be a human that bad habit destroyed the ecological environment, no one has the courage to stand up to stop. Have people unaware of the danger is quietly coming?

News often report news of casualties, such as someone because drink beverages containing chemicals and poisoning, and people were containing sand blown blind eyes... Ah! Absolutely horrible! If everyone around you endlessly environmental pollution, destruction of their homes, so, I really cant imagine that ten years, twenty years, thirty years later... Our home what happens earth-shaking changes, our descendants will blame us, what makes you denied the right to our survival!

Yeah! We dont have the privilege to damage the environment, to destroy their homes. We should not only cherish own life, more want to future generations the survival of the society in harmony with nature, for the sake of nature.

Boys and girls, lets see some action! Protect the environment, care for the home! Everyone to get rid of bad habits, start from around things, such as: dont throw away waste batteries, use water and electricity saving, try to walk or ride a bike... I believe, as long as we carefully action, and will lose everything back to nature, will be our fault compensation back. Let the future home is not painful, but the eternal beautiful young!

你们知道吗?时间不知不觉地流逝着。你们发现了吗?我们的家园变成了另一副模样：清澈见底的小河变成了污泥浊水，肮脏的灰尘充斥着空气，无处不在……这是什么原因造成了这样如此巨大的变化呢?原来是人类那不良的恶习破坏了生态环境，更没有人有勇气挺身而出去阻止。难道人们没有意识到危急时刻正悄悄来临了吗?

新闻常常报道伤亡的消息，比如有人因为喝了含有化学品的饮料而中毒，还有人被含有沙粒的风吹瞎了眼睛……啊!简直惨不忍睹啊!如果身边的每一个人都无休止地污染环境，破坏家园，那么，我真的不敢想象：十年，二十年，三十年后……我们的家园会发生怎样翻天覆地的变化，我们的子孙后代会不会责怪我们——你们凭什么剥夺了我们生存的权利!

是啊!我们没有这个特权去破坏环境，去毁灭家园。我们不仅应该爱惜自己的生命，更要为了子孙后代的生存学会与大自然和谐相处，多多为大自然着想。

同学们，赶快行动起来吧!保护环境，爱护家园!人人改掉恶习，从身边的小事做起，比如：不随便丢弃废电池，节约用水电，尽量步行或骑自行车……我相信，只要我们认真地行动起来，就一定会把大自然失去的一切都找回来，就一定会把我们的过错补偿回来。让未来的家园不是痛苦，而是永恒的美丽年轻!

吸烟对健康的危害往往使人想到呼吸系统疾病，可是吸烟还会导致视力受到影响，这不是危言耸听。

吸烟对眼睛造成最常见的危害是弱视。弱视，就是矫正视力低于0.8。吸烟导致弱视的原因，一是由于吸烟时人体吸入的氧气被消耗，致使血中氧的含量下降，而眼视网膜对缺氧格外敏感，长期下去，视神经纤维会发生变性，视网膜乳头黄斑区也会发生萎缩;二是烟草燃烧时产生的烟焦油会导致体内维生素B12的含量下降，而维生素B12是维持视神经正常功能所必需的营养物质。在这两者共同的影响下，使得吸烟者视力下降而发生弱视，严重者可致失明。

据医学家调查，在白内障病人中有20%与长期吸烟有关。而每天吸烟20支以上的人与不吸烟者相比，患白内障的可能性要高2倍。

另外，吸烟时吸入的尼古丁及一氧化碳等有害物质会使血管收缩、血小板凝集力亢进，由此导致视网膜中央血管栓塞、黄斑变性等致盲性眼病的发生。临床还观察到，吸烟者有时会有一过性眼压升高的现象，这在青光眼患者中尤为明显，青光眼病人本来眼压就高，如果再吸烟，无疑是雪上加霜。

同时，科学研究还明确指出，烟草也会导致眼睛周围的皱纹产生。即使自己不吸烟，也不应放松警惕，“二手烟”“三手烟”同样会摧残身心和容貌。因此，我们还是和烟草保持一定距离吧。

我们人类生活在地球上，地球上有许多东西需要我们保护，但是我们却没有在意。

We live on the earth, the earth there are many things we need protection, but we didnt care.

有些人不珍惜地球赐予我们的一切，例如人们乱砍乱伐，大量使用一次性筷子和乱扔塑料袋，制造白色垃圾等已经给大自然带来了许多环境问题，严重影响了我们的生活。还有大气污染，酸雨和臭氧层等带来的危害都是大自然给人类带来的灾害，人们乱砍乱伐，乱扔塑料袋和使用一次性筷子等，这些就是人们不尊重大自然而造成的，没有自然，便没有人类。这是世界一大朴素的真理，人们只会一味的抢夺自然，征服自然，只会破坏生态系统，咎由自取，使人类濒于困境。切记，保护环境就等于保护我们自己生存的环境。

Some people do not cherish the earth gives us all, for example, people cut down many trees, the extensive use of disposable chopsticks and throw plastic bags, producing white garbage has to nature brought many environmental problems, a serious impact on our lives. There are air pollution, acid rain and the ozone layer damage caused is human nature to bring disaster, people cut down many trees, throw plastic bags and disposable chopsticks, which is that people do not respect the nature and cause, no nature, no human beings. This is a big world, plain truth, people just blindly grab the nature, conquer nature, will only bring trouble to oneself, the destruction of the ecological system, humans dilemma. Remember, Protect environment is to protect our own living environment.

我们要保护这个脆弱的的地球，不要让茂密的森林，辽阔的草原和无边无际的海洋成为我们的回忆。

We want to protect this fragile earth, dont let the dense forests, vast grasslands and boundless ocean has become our memories.

现在起，我们应该保护环境，一起捍卫我们的家园。

Now, we should Protect environment, to defend our homeland.

Panda is known as the national treasure of China. The panda was a kind of ordinary animal in China long ago. However, for some reasons, too many of them have been killed. So the number of them is falling quickly.

At present people are taking an important measure to save pandas. People want to find a home for them, and recently, they have set up a nature park for them in Sichuan Province,which is called "Pandas Home. "There pandas can enjoy their life happily. There is a bamboo forest near the Pandas Home. So the pandas can find bamboos easily which they like to eat very much.

Because pandas are well protected now, the number of them is increasing every year. We hope that one day we will have enough pandas to set them free and let them live in the wild again.

Pandas are good friends of man. Man should try to protect them and ]et them live in the way they like!

"Protect the environment, everyone duty", when it comes to protecting the environment, I think of a thing.

Its a sunny afternoon, my mother and I happily went downstairs for a walk, inadvertently, I found on the green lawn with an old, dirty battery. Battery is harmful to our environment a major killer! A grain of small button battery can be 600 cubic meters of water pollution, the equivalent of a mans lifes water consumption; Section 1 battery rot in the field, can lose one square metre of land utilization value, and cause permanent public nuisance. Think about this, I ran to my mother had said it again, I say again: "mom, I want to throw waste batteries into the dustbin." Mother think I speak very reasonable, I happily run to waste batteries, thought: I really do a meaningful thing! I gently picked up the waste batteries, threw it into the dustbin.

"Not to small and not for good, it is a sin to." As a primary school student, we should start from me, start from small things, start from the side, start from now, pick up every piece of paper on the ground, take good care of trees and flowers, love small animals. Lets go and look for the green world, to make our world a better place!

“保护环境，人人有责”，说到保护环境，我就想起了一件事。

这是一个阳光明媚的中午，我和妈妈高高兴兴地下楼散步，无意中，我发现在绿油油的草坪上有一个废旧的、脏兮兮的电池。电池可是危害我们生存环境的一大杀手!一粒小小的钮扣电池可污染600立方米水，相当于一个人一生的饮水量;一节一号电池烂在地里，能使一平方米的土地失去利用价值，并造成永久性公害。想到这，我跑到妈妈跟前把这件事儿说了一遍，我又说：“妈妈，我想把废电池扔到垃圾箱里。”妈妈觉得我说得很有道理，我欢快地跑到废电池旁边，心想：我真是做了一件有意义的事啊!我轻轻地捡起废电池，扔进了垃圾箱里。

“勿以善小而不为，勿以恶小而为之。”作为一名小学生，我们要从我做起，从小事儿做起，从身边做起，从现在做起，捡起地上每一片纸屑，爱护花草树木，关爱小动物。让我们一起去寻找绿的世界，让我们的世界变得更加美好!

Now it is common that students copy homework from their classmates. I think it is a terrible thing . Because homework is their own task and the check for what they learn in class. If they copy others homework , the teachers wont get the fact so they cant help the students to improve. Besides ,if the students cant finish their homework, they cant get the chance to go over their lessons so they cant make progress. So dont copy others homework.

Dear humans, I have to write to you because my friends are dying.The reasons are as follow.First,you damage the forests and take up too much land where we live.Second,you humans even kill the endangered animals for food,many of us have been killed over the past years.But as you all know,animals and humans are good friends.We live in Earth,relying on each other.Without animals,humans wont live long.So,humans should protect animals,that means protecting yourselves. Best wishes Yours Panda

The Marine life environment is a complex system including seawater, sea water content and suspension, seabed sediment and Marine life.The abundant biological resources, mineral resources, chemical resources and power resources of the sea are the indispensable resources of human beings, which are closely related to the survival and development of human beings.

The main objective of Marine conservation is to protect Marine life resources so that they are not depleted for sustainable use.Special priority should be given to protecting Marine life that is valuable and endangered.According to the relevant departments of the investigation, due to overfishing, accidental killing of non-target to allow hunting of Marine, coastal tidal flats in the engineering construction, mangrove deforestation, widespread Marine pollution, at least 25 in the worlds most valuable fisheries resources exhausted, whales, turtles, manatees and many other Marine animals are in danger of extinction.With the expansion of Marine development, the potential for greater damage to Marine biological resources is expected.

Marine conservation of the first task to stop the excessive use of Marine biological resources, secondly we must protect Marine habitats or niches, especially their migratory, spawning, feeding, avoiding DiHai coast, beaches, estuaries, coral reefs, to prevent the heavy metals and pesticides, oil, organic matter and eutrophication of nutrients, such as pollution of the sea.To maintain the renewable capacity of Marine biological resources and the natural purification capacity of seawater, maintain the balance of Marine ecology and ensure the sustainable development and utilization of the sea.

人看东西，无论是看远、看近都是靠眼球和管眼睛的肌肉来调节的。许多同学在看书、写字的时候距离书本很近，而且一看就是很长的时间，弄得眼睛很疲劳;也有很多同学喜欢一面走路一面看书，躺在床上看书或在光线不足的地方看书，这样天长地久以后，管眼睛的肌肉疲劳了，眼球里面的晶壮体也变形了，这些同学也就变成近视眼患者。患了近视眼的同学，需要及时配戴近视眼镜矫正视力，当然还得比常人更需要注意用眼卫生，不要使近视加深。

同时，没有患近视的朋友，要养成用眼习惯：一、要端正读写姿势，要保持读书、写字的姿势端正，必须遵守三点要求：眼与书本一尺远;胸与桌子距一拳;笔尖与手指一寸远。二、用眼不要持久，持续读书写字1小时左右要休息片刻。三、看电视用眼要卫生。明白长时间看电视会损害视力，会导致眼肌调节紧张和疲劳，造成近视。

其实，补钙也可以防近视。众所周知，维生素A缺乏时对儿童视力有不良影响，钙缺乏也同样会造成儿童视力减退。

如果儿童膳食中缺钙就会引起神经肌肉兴奋性增高，使眼外肌处于高度紧张状态，再加上少年儿童做作业时间长，不注意用眼卫生，共同造成眼球调节的时间增加，增加了眼外肌对眼球的压力。

Recently we have held a class meeting to discuss what is considered to be honorable behavior and what is shameful.It is really a pity to see all this in our school.Some students don’t respect their teachers or parents. Some don’t take their studies seriously and cheat in exams. Some throw wastes everywhere and pollute the environment . It is honorable to obey the law and rules , care much about our class and study hard.It is shameful to break school rules, to be selfish or to make little effort to achieve success.We should respect others and think more of them than of ourselves.We should work hard and make much more progress to repay the society.We should try our best to keep the environment clean。

Now, people dont speak hygiene, make the earth became very clean.

Factory waste water into the river discharge, discharge waste water will not think about it, if people drink the water, what will happen?

Also, people cut down trees, on the lawn, people will think of these things, without the trees, how do we have the fresh air and oxygen, no grass we how green home! Besides, if sandstorm comes, without the trees blocking, what will become of our home.

Why are both street trash can, this is to remind people not to throw rubbish everywhere, put the rubbish in the garbage can. But, a lot of people love throwing garbage everywhere, this kind of behavior not only damage the image of our home, what also polluted the earth again.

I want to tell everyone: "protecting the environment is to love life!" To protect the environment, we should start from the side, starts from me, to build our homes more beautiful!

现在，人们都不讲卫生，使地球变得很不干净。

工厂里的废水向河里排，排废水的人会不会想想，如果人类喝了那些水，会怎么样?

还有，人们砍伐树木，踏入草坪，做过这些事的人会不会想想，没有了树木我们怎么有新鲜的空气和氧气，没有了小草我们怎么绿化家园啊!再说，如果沙尘暴来了，没有了树木的阻挡，我们的家园会变成什么样。

为什么街道旁都有垃圾桶，这是提醒人们不要随地乱扔垃圾，把手中的垃圾扔进垃圾桶里。但是，很多人都爱随地扔垃圾，这种行为不仅损坏我们家园的形象，还让地球再一次的被污染。

我想告诉大家：“保护环境就是爱护生命啊!”要想保护环境，就要从身边做起，从我做起，把我们家园建设得更加美丽吧!

In a sunny afternoon, the air was fresh, coconut particularly lush, xiao gang holding tank and nets, walked at a brisk pace, happily to catch frogs.

Xiao gang came to the pond, the skylight, just caught a crock of frogs. He happily ran home, sitting on the sofa, drinking beverages, listening to the tape recorder, want to relax, and behold, a passage from the recorder "again today to the voice of the animals, play time, please dont catch frogs to protect the frog." Xiao gang wish: everyone in catch frogs, why not let me catch! Xiao gang is very angry, he took out the animal encyclopedia started flipped up and found that it turns out that the frog is secondary to protect animals, and was little tadpoles mom, I used to love this book "little tadpole looking for mom".

Ashamed, at once, xiao gang immediately ran out of the house, run out whole body energy, rushed to the pond and the frog and little tadpoles released, little frogs in the pond croaked and cried, as if to say: "thank you!" Xiao gang also said softly: "go, go find your loved one!"

Through this story, I know a small token, that is: to protect the frog, everybody is responsible for.

在一个风和日丽的下午，空气十分清新，椰子树格外茂盛，小刚拿着鱼缸和鱼网，迈着轻快的步子，开开心心地去捉青蛙了。

小刚来到池塘边，费了九牛二虎之力，才捉了一缸青蛙。他高兴地跑回了家，坐在沙发上，喝着饮料，听着录音机，想放松放松，不料，录音机中传出一段话“今天又到了动物之声的播放时间，请大家不要捉青蛙，要保护青蛙。”小刚心想：大家都在捉青蛙，为什么不让我捉!小刚十分生气，他拿出《动物百科》开始翻阅起来，发现，原来，青蛙是二级保护动物，而且竟是小蝌蚪的妈妈，我以前最爱看《小蝌蚪找妈妈》这本书。

顿时，小刚感到羞愧万分，立即跑出家门，用尽全身力气，冲向池塘边，把小青蛙与小蝌蚪放生了，小青蛙在池塘边呱呱地叫着，好像在说：“谢谢你!”小刚也轻声说道：“去吧，去找你们的亲人吧!”

通过这个故事，我知道了一个小道理，那就是：保护青蛙，人人有责。

Environmental protection, the subject, is a household name, everyone knows. But in real life, some people still dont too seriously, think small, in my opinion, environmental protection should start from the pretty little things. I have experienced such two things: one day, I go to the supermarket to buy things, quickly to the door of the supermarket, see several send out flyers, see to, see cars, but some people dont, casually throw on the ground, I used the paper in the trash. Saw the two men, the propaganda time with glue on the wall, from a distance, like pieces of "psoriasis" while they do not pay attention to, and I took out my skills "tearing work", ha ha, I get rid of a large "psoriasis" is. At another time, I play in the bottom of a floor, find the distance on the grass up whereas white smoke, a closer look, it turns out that there is a group of children in our class burning grass, grass black a large, I hurriedly stop as a big brother, and about the dangers of fire and the importance of environmental protection. They are ashamed, quickly the coming water from the nearby end extinguish fire, finished burning grass action.

We human beings are living on a planet, that is the earth. On earth, have for the oxygen we breathe, there are dense forests, vast grasslands, boundless sea, all kinds of animals, constitute the beauty of nature.

I think loudly called on the people: the earth belongs to our human, belongs to all of us, as long as with our hands, starts from me, starts from everyone, protect the environment, the love of the earths natural resources, make clear pond water still flowed in the home, flowers in full bloom the flowers still.

Human ah, should be time to wake up, open your eyes and look around us, this is our home, let us from now on, wash his with their own hands, with their own wisdom, with their own conscience, for our children and grandchildren keep a harmonious and beautiful homeland, let us make an efforts to us from generation to generation for survival!

环境保护，这个话题，可以说是家喻户晓，人人皆知。但在现实生活中，一些人还是不太重视，认为微不足道，在我看来，环保要从件件小事做起。我就经历过这样两件小事：有一天，我去超市买东西，快到超市门口时，看见有几个散发宣传单的，见人就给，见车就放，可是有些人却不要，随手就扔地上，我过去将纸扔进垃圾箱里。又看见两个人用胶水将宣传单贴在墙上，远远望去，活像一块块“牛皮癣”趁他们不注意，我又拿出我的绝活“撕纸功”，哈哈，“牛皮癣”被我除掉了一大片。还有一次，我在楼底玩，发现远处草地上冒出了缕缕白烟，走近一看，原来，是我们班一群小孩在那里点火烧草，草黑了一大片，我以大哥哥的身份连忙制止，并讲了火灾的危险性和环保的重要性。他们羞愧难当，赶忙从附近端来水把火熄灭，结束了烧草行动。

我们人类都生活在一个星球上，那就是地球。地球上，有供我们呼吸的氧气，还有茂密的森林、辽阔的草原、无边无际的海洋、各种各样的动物，构成了美丽的大自然。

我想大声呼吁人们：地球属于我们人类，属于我们大家，只要用我们的双手，从我做起，从人人做起，保护环境，爱护地球上的自然资源，让清澈的塘水依旧流淌在家乡，让花儿依旧那样鲜花盛开。

人类啊，是应该觉醒的时候了，睁开眼，看看我们的周围，这是我们的家园啊，让我们从此金盆洗手，用自己的双手，用自己的智慧，用自己的良心，为我们的子子孙孙留下一个和谐、美丽的家园吧，让我们为我们世世代代的绵延生存做出一份努力吧!

Although the world develops much faster and better, the resources on the earth get fewer and fewer.In order to protect them,something must be done.尽管世界发展得更快、更好，地球上的资源越来越少。为了保护他们，必须做些什么。

Save water. Water is the source of life. No water, no life. So its very important for us to do so.Not only should we protect drinking water and stop polluting it, but also make full use of it.节约用水。水是生命之源。没有水，就没有生命。所以这是非常重要的我们这么做。我们不仅要保护饮用水和停止污染，而且充分利用它。

Save electricity. It is crucial. We cant imagine what the life will be like without it.Everyone should do his best to save electricity. Dont forget to turn off lights or other electric machines when we finish working.节约用电。这是至关重要的。我们无法想象的生活就会像没有它。每个人都应该尽自己的最大努力节约用电。不要忘记关灯或其他当我们完成工作的电机。

Save forests. They are useful .Please stop cutting them down and use recycled paper instead. Make our world a green one to live in.拯救森林。他们是有用的。请停止切割下来，用再生纸代替。使我们的世界成为一个绿色的生活。

Recycle useful rubbish. Plenty of rubbish can be recycled like cans,paper, bottles, and so on. We can save resources in this way.回收有用的垃圾。大量的垃圾可以回收罐，纸，瓶，等。我们以这种方式可以节省资源。

we all know that the panda is a kind of lovely animals, but its behavior, some children are not completely know. In order to solve this mystery, recently I have made an observation about it.

The panda is a kind of precious animal, is very attractive. Its shorter in four rubber slow action. On the face of fuzzy embedded with a pair of black eyes. Combined with a black and white hair, more beautiful and lovely.

Pandas like to walk leisurely on the flat ground, play happily. Sometimes looked up people, sometimes low head, as if in search of something, and like to think. When it is happy, somersault on the ground, like a big ball rolling on the ground.

The panda when sleeping, belly up. Sometimes, patting his stomach with his front PAWS, sometimes, it push to the legs, was turned over. I thought it waked up, in fact, it is still in sleep. Waked up just turn it up, with his front PAWS rubbed his change to eyes, curiously at the people, with for she walked away to the other side of the fence to sit down, as if to clear his mind. (pupil composition nets)

When the panda eat, often straight body sitting cross-legged, PAWS grab fresh bamboo leaves to her mouth. It loves to eat fresh bamboo leaves, bamboo stem, and milk and eggs. Pandas eat and drink drink throat. It came to the pool, fell down, the ball pool, lower the head, plump plump to drink up. See the face of it, really makes people laugh.

The panda is one of the worlds rare animals, is a darling of the zoo. Its every move, add fun to tens of thousands of visitors.

Animals Need Protecting

Earths biological diversity is being fast decline of many species facing extinction. Threat to the survival of wild animals and plants is a major factor in habitat loss, business development, and wild animals and plants and their products in international trade. Resources are limited, it is necessary for the endangered species, to propose specific measures of protection level. We can formulate the corresponding endangered species laws, application to establish nature reserves, endangered species breeding centers, means of conservation biology, endangered species, the implementation of in situ conservation and ex situ conservation. At the same time, we must restrict international trade in Endangered Species of Wild Fauna and Flora, to make laws to protect endangered species.

我们能看见美丽的世界；能看到美丽的花朵；能看到世界万物所有的东西，知道是谁的功劳吗？——眼睛。

如果没有了眼睛，你将看不见世间所有的东西；如果没有了眼睛，你的一生都是黑暗的。如果你现在不好好珍惜，等到失去了，就不会再回来了。才会知道眼睛的重要性。有的人把眼睛当做一个摆设，只是为了好看；有的人把眼睛当做一个棋子，只是为了与别人一样，都有眼这一个器官，而有的人，把眼睛好好保护着，好让他看到世间更美的东西。大家都知道，世界上是没有卖后悔药的，所以，为了我们不会后悔，从现在开始，就让我们好好保护眼睛吧！

我的眼睛，从小学到六年级上册都是很好的，可就是因为在放寒假的时候，整天就知道看电视，玩电脑，看书写字都是趴着，晚上还经常熬夜，导致了我现在的视力大不如前了。自从听了讲座，让我感到很后悔，可我知道，世界上是没有卖后悔药的，所以，我现在要好好保护我的眼睛！要想保护好眼睛，要做到以下几点：

1：看书不能太近。2：不能长时间玩电脑，看电视。3：要经常运动。4：要有合理光源，要把灯放到左上角。5：要营养充足。6：睡眠要充足。

我们要对我们的眼睛负责，不能伤害我们的眼睛。我们一定要有保护眼睛的意识，让我们从现在开始，好好保护我们的眼睛吧！

教师评语：小作者用自己的亲身经历告诉我们近视眼的原因及危害。从而呼吁我们青少年从现在开始保护好我们心灵的窗户——眼睛。感情真挚，语言富有亲和力。

The environmental protection is the most major problem which in the modern life the humanity faces. Must solve this problem must start from foundation. First, must massively propagandize, enhances peoples consciousness with understanding, strengthens the environmental protection consciousness. Next, must carry on waste recovery use, reduces to forest-trees felling. Also must strengthen to white pollution processing, little uses the plastic product. Finally, must make improvement to clean aspect. Causes the citys appearance to be neater. For Earths tomorrow, we must start from the now diligently, will want the well local constable to protect the environment. To this us proposes as follows suggests: Implementation trash classification packed in bags. Like this not only can reduce the environmental sanitation workers work load, but also can even better basically arrive makes use of waste, to reduce the pollution, saves the resources.

环境保护是现代生活中人类所面临的最主要问题。要解决这个问题必须从基础做起。首先，要大量宣传，提高人们的意识与理解，加强环保意识。其次，要进行废物回收利用，减少对森林树木的砍伐。还必须加强对白色污染处理，少使用塑料制品。最后，必须改善清洁方面。使城市的外观整洁。为了地球的明天，我们必须从现在开始努力，将希望和当地的警官保护环境。为此我们提出如下建议：实施垃圾分类袋装。这样不仅可以减少环卫工人的工作量，而且可以更好的利用废物，减少污染，节约资源。

Xitang, a beautiful scenery, the scenery pleasant, pond water bottom, little fish in the water, the ducks on the water, and a variety of unknown elf dallied, men weeping willows graceful, flowers to outshine each other... But then xitang is changed.

Xitang, turned into a "dump". Pond floated on the surface of a lot of garbage bags, sometimes floating in the pumpkin. Below the surface are all black skin mud, and people have lost. How to make the town is not contaminated?

From now on, we have to clean the bottom of the pond sludge, dont let the pond water in xitang, well have some trash can, men and also made some billboards, told men store boss and passing pedestrians dont litter.

Let us act, to join protect xitang environment! I believe in the near future, xitang must be as beautiful as before.

以前的西塘，景色优美，风光宜人，塘水清澈见底，小鱼儿在水中漫步，野鸭们和各种不知名的小精灵在水上戏耍，塘边垂柳婀娜多姿，花儿争奇斗艳……可后来西塘却变了。

西塘变成了“垃圾场”。塘面上漂着许多垃圾袋，有时还漂着臭南瓜。水面下全都是黑黑的泥和人们丢的果皮。怎样才能让西塘不受污染呢?

从现在开始，我们要清理塘底的污泥，不让塘水流进西塘里，我们要塘边放一些垃圾桶，还要立一些告示牌，告诉塘边商店的老板和过往的行人不要乱丢垃圾了。

让我们行动起来，加入保护西塘的环境的行列中去吧!我相信不久的将来，西塘一定能像以前那样美的。

最近，妈妈经常提醒我看书的时候眼睛离书本远一些，可是我看着看着就不自觉地凑得越来越近，眼睛也又干涩又疲劳，总觉得看不清远处的物体。妈妈带我去医院一检查，原来是近视了。

我觉得很纳闷，为什么有些同学的视力特别好，坐在教室后排也能看清黑板上的字，而我却得了近视，看到的字都是模模糊糊的?为什么得了近视看物体就会模糊呢?

带着一连串疑问，我翻阅了许多资料，终于明白了其中的奥秘。这得从人的视力形成的原理说起。我们视线内的物体反射的光进入眼球，落在视网膜上，我们就可以看到物体。人的眼睛有三个解剖学系统：光学系统、肌肉系统和神经系统。光学系统用来收集和聚集来自视野中物体光线的反射，肌肉系统帮助眼球运动，神经系统则把光能转化为电冲动，并把信息传递给大脑，形成视觉图像。正常的视力需要这三个系统保持正常的机能，共同协作，完成任务。

我平时喜欢趴在课桌上写字，也很喜欢玩电脑，眼睛长时间看着近处的物体(书和屏幕)，眼睛的肌肉系统就缺少运动和调节。这个环节出了问题，形成的视觉图像也就不清晰了。再看看那些视力好的同学，多半看书姿势比较好，而且长时间看书后会都休息一会儿。这样，眼睛的肌肉系统就能劳逸结合，正常工作了。

了解了近视形成的基本原因以后，我下定决心好好保护视力，再也不要趴着写字和长时间玩电脑了。我也决心学习更多的科学知识，更好地保护自己。
